本文主要介绍VFN150/8往复式高粘液计量泵的结构、机理及粘度为10万CP以下的葡萄糖液的试验结果,探讨泵在高粘液下主要参数之间的关系以及提高容积效率和计量精度的途径等。一、参数和结构特点 VFN150/8往复式高粘液计量泵的传动调节机构、驱动电机和普通计量泵一样,不同的是前者具有高粘度液泵缸头,见图1。泵的基本参数最大流量 150 l/hr 排出压力 8kgf/cm~2 往复次数在n=25rpm以下作无级调速行程长度 S=88mm(从0～88mm手动
This article mainly introduces the structure and mechanism of VFN150 / 8 reciprocating mucus metering pump and the test results of glucose solution with viscosity less than 100,000 CP, and discusses the relationship between the main parameters of pump under high mucus and the improvement of volumetric efficiency and metering accuracy Ways and so on. First, the parameters and structural features VFN150 / 8 reciprocating mucus metering pump drive adjustment mechanism, the drive motor and ordinary metering pump, the difference is that the former has a high viscosity liquid pump cylinder head, shown in Figure 1. The basic parameters of the pump The maximum flow rate 150 l / hr Discharge pressure 8kgf / cm ~ 2 reciprocating frequency Under n = 25rpm for stepless speed regulation Stroke length S = 88mm (from 0 ~ 88mm manual
